Preconcentration of Scandium from Rock Matrix Using the Silica Modified with Tributyl Phosphoric as Solid-Phase Extraction and Determination by GFAAS.
Article in ACS omega, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The scandium in an ore with the scandium content less than 1 ppm is analyzed by graphite furnace atomic absorption spectrometry (GFAAS). We had applied solid-phase extraction as preconcentration and used the silica modified with TBP as an adsorbent. Using the silica modified with TBP, after the separation of the solid phase, the slurry of the adsorbent was made for the direct injection of the adsorbent into the graphite furnace. The absorption capacity of silica modified with TBP for scandium was 3.54 mg/g. The conditions for the correct analysis of scandium were as follows: the pH of absorption was 5 and the time of absorption was 30 min. The slurries were prepared in a solution containing 100 μL of 1% Triton X-100.
